I have noticed that the following example will result in the header From:
entry being overwritten.

helo realdomain.com
mail from: <joe>
rcpt to: <wietse>
data
From: <wietse>
.

My understanding of the header From entry is the one that is derived from
the mail from: line in the attached example. A header check for
joe will fire as expeceted on this test so I"ASSUME" that
my definition is correct. The mail that postfix delivers replaces
the From: <joe> with From: <wietse> into the
header of the delivered mail. Once again thanks in advance for your help.
